We have a WPF application that is using Telerik UI for WPF version 2017.3.913.45. I am making changes to the application and began to use the latest version 2019.1.220.45. The primary reason I used the latest version is grid paging. I have a few questions. 

1. Are there compatibility issues if we move our application to the latest version?  If so, where can I find a document which outlines those issues? The application compiles fine. I'm concerned about run time issues.

2. Is paging supported in the earlier version (2017.3.913.45 - it appears that it is not)? 

3. I did go to the download page to see if the earlier version (2017.3.913.45) has any DLLS that I'm missing which may have the paging functionality. I was not able to find this version in the list to be downloaded. Where can I find that version (in case I would like to use additional functionality)? See the attached screen shot which shows that it is not available in the list.

Thanks.

Hello Thomas,

Let me get straight to your questions.

  1. Are there compatibility issues if we move our application to the latest version?  If so, where can I find a document which outlines those issues? The application compiles fine. I'm concerned about run time issues.

    Upgrading to the latest version should not cause issues when it comes to the runtime. However, there might be breaking changes that will be noticed at compile time. You can check what changes were introduced between 2017 and 2019 in the Release History page. Also, you can use the API Analyizer tool to see potential upgrade issues with the API.

    Also, please keep in mind that minor updates are constantly introduced to the product, so there is no grantee that there will be zero issues. This is why I would recommend you to test your application well after the upgrade.

  2. Is paging supported in the earlier version (2017.3.913.45 - it appears that it is not)? 

    Can you tell me what paging you mean and why it doesn't work with the 2017 version on your side? Usually, paging is implemented with the RadDataPager control which is available also before the 2017 releases. 
  3. I did go to the download page to see if the earlier version (2017.3.913.45) has any DLLS that I'm missing which may have the paging functionality. I was not able to find this version in the list to be downloaded.

    In your telerik.com account you see version of the products for the periods you had a valid license. If you don't see versions before 2017.3.913.45 that probably means that there weren't a license assigned to your account during this period. To see earlier version I would recommend you to open a new support ticket from your account and request the desired version there.
